Bluetooth pairing not working on all devices

[Tomas Öqvist]

Nexus 4 with MultiROM, utopic r235

There ar, a few bluetooth devices that still don't work together with Ubuntu Touch. These devices work perfectly well when booting the phone as Android. The devices that fails to connect for me are BlueAnt Supertooth 3 (http://www.myblueant.com/shop/us/products/st3.php#related) and My Volvo car bluetooth system, both with Bluetooth version 2.0 specifications.

With BlueAnt Ubuntu can discover the unit and attempts to connect, opening a pairing dialogue with the digits "0000". Confirming the pin code (which is correct) doesn't do anything, my Ubuntu phone is not recognized by BlueAnt and won't show as a connected device in the phone's bluetooth settings, but shows up under "Connect other device followed by ..." The bluetooth indicator, however, shows as connected.

With My Volvo Car, pairing works differently. The bluetooth system in the car searches for devices and shows "Nexus 4" and then prompts me to connect with a 4-digit pin code, but the Ubuntu phone doesn't react at all and after a while the car system says that it failed to connect.

Oh, adding to that, the indicator remains "lit" even after turning BlueAnt off and toggling Bluetooth off/on in the phone settings.

Status changed to 'Confirmed' because the bug affects multiple users.

It is one of the essential function of a phone connecting to a car headset. With my Mecedes Benz the pairing starts. Ask me for the couple code. I put '0000' to pair the system. It seams to be connecting at the phone. For some seconds at the phones display I can read 'connect'. But, the car system still waiting for some additional data and disconnect finally the phone.

Maybe this could be merged into some of the other bluetooth-indicator bugs?

I am no longer using Nexus 4. I have switched to a Pro 5. The problem there is the noise that comes with using the phone with a bluetooth headset or in-car system, according to this bug https://bugs.launchpad.net/canonical-devices-system-image/+bug/1590844.
